*IIVIPROVEMENT IN VAPOR-BURIIERS.

The Schedule Men-e616 in than Letters Patent and making part of the lame.

To all whom it hwy concern.-

Be it known that I, SAMUEL Homnns, of 180 High Holborn, in the county of Middlesex, England, a sub-. ject of the Queen of Great Britain, have invented or discovered a new anduseful Improvement in Lamps for Burning Volatile Oils and Spirits, and I, the said SAMUEL HOLMES, do hereby declare the nature of the said invention, andin what manner the same is to be performed, to be particularly described and ascer-.

tained in and by the following statement thereof that This invention has for its object the improvement of lamps, for burning volatilemils and spirits, by constructing'them in such manner as to insure perfect safety from explosion, and also the complete control of the light. 7

These objects are obtainedby combining in the same lamp the tbllowing peculiarities, viz:

First, the insulation .of the parts heated by the flame, from the vase or reservoir, by surrounding such parts by a casing containing a non-conductor of heat, and reaching to the bottom of the vase or thereabouts.

Second, a valve arranged in the upper part of the burner, and operated by a screw or other means.

Third, a packed joint, which permits the movement of the valve without permitting the escape of the volzv tile vapor, except at the perforations of the'burner.

The lamp-burners, represented in the accompanying drawings, show several modes in which I have contemplated the application of the principle of my invention, the reservoirs of oil being omitted in the several figures.

In the construction represented at Figure 1, a is the cap or collar, which is secured by cement to the top of the reservoir, and b is the gallery to receive the globe. and is provided with a tube, b, which descends through the cap to the bottom of the reservoir, where it is connected with the lower end of the wick-tube c, which re ceives the wick, in the ordinary way. The tube b, thus arranged, forms a casing, which insulates the wick-tube from the fluid in :thereservoir.

The wick-tube is surrounded bya tube, 5, which is constructed to slide upon it, and has the button a secured to its upper end. This sliding tube 1'. is perforated, as at i, below the button, to permit the vapor This gallery is screwed fast to the cap, 0,.

There is a packed, gas tightjoint, 3;, between the wick-tube q and the sliding tube 1, which joint prevents the escape of the vapor, while permitting the outer tube to slide upand down. The vapor generated in the wick-tube escapes into the outer tube, and is burnt as it issues from perforations, 11', therein.

4; is a valve-plug, formed on the under side of the top of the tube 6, and which,'when this tube is in its .end, which works into a corresponding screw, b fixed within the tube b.

i is a ring, connected by arms with the tube i, and by it the tube can be turned partly round, to obtain the desired regulation or extinction of the flame by raising or lowering the tube a? by the screws, thus opening or closing the valve 2:. The arms which carry'the ring i are intermediate of those which carry the gallery for the glass.

Figure 2 shows a. similar lamp, except that the vertical movement of the tube 6, by which the valve 6 is opened or closed, is here obtained by alever, 13 jointed to the gallery and to the tube, and which is pressed upwards by a spring, 11, and depressed by a screw, 5, acting upon an inclined plane at its end.

Figure 3 again shows a similar lamp, but here the tube iis prevented turning upon the wick-tube by a stud and-slot, o, as is shown, and the screw at its lower end works with a screw at the lower end of a tube, k, to which the disk It is connected by arms.

What I claim, is-- 1. The combination of the insulating-casing, the packed, gas-tight joint, and the valve, constructed to .operate substantially as before described.
